Walt--- great story. You're absolutely right. You know all the 'stick
time' that we accumulate during the building
process ? Well in all the times I was sitting there moving the stick
around on the ground I it never once crossed
my mind that something should break......but on climb-out during my first
flight I suddenly got this unwarranted sense
of caution that those wing struts are holding the entire weight of me, my
fuel, my engine, my fuselage, and my landing
gear...and if they should fail now, I'm going down. After rationalizing
to myself that I knew that I knew that every part
of the plane was made to the best possible standards out of the best
possible materials and inspected by several very
knowledgeable people, that I was fine and should just enjoy the ride and
the first flight. (and all the following flights:)
The older guys at our airport are really good (like your Dick Lawson) and
do everything the right way on maintenance
and restorations, but the one guy will finish a job, show it to me, and say
"it's good enough for who it's for." and of
course he's joking--but its still funny.

Another common question is this one and my answer always surprises
people. I tell them that you can legally fly
a plane like our from coast to coast without ever having to talk with
anyone at anytime. My first two times to Oshkosh
I went 100% non-radio in 1998 and 1999. Since then they have really
tightened up the rules on NORDO approaches
to Oshkosh, but it still can be done.
Since then I bought myself a nice Icom handheld and really find between
that and a puff or two of smoke in the pattern
increases my safety and of those in the air around me.

Just the kind of responses I get also Walt whenever I take someone out to
the garage. Funny when you fly in a plane someone else built (including a
factory) you don't think about welds failing and bolts falling out (at least
I don't). You just assume that anyone that builds something as complex as an
airplane must know what they are doing, that is unless I built it. I am sure
that when I get this thing in the air some day and I hit some good
turbulence I will immediately flash back to the welds on the flying struts
and fittings, the T-88 holding the floor on the plane and keeping me from
falling out the bottom, etc.

Hi Dick
Our gliders use a stiff milar taped to the hor stab & vert stab.
My glider has closed cell foan glued to both surfaces with contact cement.

Subject: Pietenpol-List: gap seals
I know that gap seals hve been discussed before, but I just want to ad a bit more
to it. At Broadhead I had discussed my takeoff problems with a few of you.
If I wasn't careful and didn't add power slowly, while pinning the stick foward,
the plane would want to fly before it had the speed. This would cause the
plane to want to stall at the ground. I thought this might be the way a Piet
flew.
After telling my story to the old timers sitting around after all had left, they
told me not to look at moving the gear aft as I was thinking but to gap seal
the elevators. I have piano hinge on the ailerions so I hadn't thought much
about the elevators.
After locating some duct tape at Brodhead I taped up the elevators. Right away
it flew like a completely diffrent plane.
It is much easier to handle on takeoff, tail comes right up and the stick is much
lighter. On landing it is more responsive. In cruise it adds about 2 mph.
My only question in all of this is, what to replace the duct tape with for a permanent
addition? My first thought is a closed cell foam that we use at work
as an expansion joint in concrete. Next might be strips of leather or a mylar
tape.
Any suggestions?

controllers ??
| Subject: | Re: do you have to talk with air traffic |
controllers ??
--> Pietenpol-List message posted by: Jim Ash <ashcan@earthlink.net>
Years back some friends came to me after reading about a recent plane crash at
a local grass strip in the Orlando Sentinel. The writer had volunteered a comment
in the article that there was no control tower at the airport (no relevance
to the accident, obviously). The article implied that airports without control
towers were unsafe. My friends were shocked to read this 'news'.
I asked them why they weren't shocked that there weren't traffic lights at every
intersection of two roads, and how they managed to survive 4-way stop signs
every day.

| Subject: | Options decisions |
--> Pietenpol-List message posted by: Jim Ash <ashcan@earthlink.net>
I just got two of Tony Bingelis' books. I promised myself I was going to read them
before I started an airplane, and I'm glad I have so far.
I I read, I've had some questions about options specific to the Piet. I've got
the plans, including the supplementals and 3-piece wing drawings. I'm just trying
to decide what makes sense for me. I'm 6'2" and 200lb, so I expect the long
fuselage and the seat setback will be in order. I haven't put together a mockup,
but it's coming.
I was planning on building the 3-piece wing, but then I read that the typical three-piece
wing adds significantly more weight to the plane. Now I'm wondering
if this holds true specifically for the Piet.
I've also seen comments that the Piet tube-and-fabric fuselage is significantly
lighter than the wood one. I'm comfortable welding 4130 tubing, so I can go either
way.
I currently own a J-3, but if I take my wife for a ride, I'm about 70 lb over gross,
so useful load in an airplane is one of my hot buttons. I'm not going to
set myself up again for this problem, certainly not from the start, anyhow.

| Subject: | Re: lift strut strap buckling |
If it is the strap between the gear fittings on each side that you are talking
off, Greg and Dale have them on their pietenpol. The strap takes the tensile
loads and the ash takes the compressive loads.

Subject: Pietenpol-List: lift strut strap buckling
Jeff,
I too have seen this on many Piets, typically in the front strap.
It must be hard landings where not only is the lift strut loading that strap
in compression, but the gear bungee attachment is pulling that strut fitting down
at the same time. I think this introduces a kind of downward "rolling" motion
in that fitting which wants to buckle that belly strap.
Most people just add more bolts.
Interesting note, I've never seen it on a axle-geared Piet.
Good luck
Douwe

that is what greg and dale get from their 72 42 homebuilt prop copied from an old

That's about what I get from my homebuilt 72 X 42 prop, with Cont. A65 engine.
I added aerodynamic fairings to the gear legs, and jury struts, and now I have
to hold some forward stick pressure. I plan on removing the fixed trim tabs
on the flippers. The fairings helped clean up the parasite drag, a little
bit.

Does anybody know where I can download, in pdf format, the entire FAR part 23 on
light airplane certification. It normally goes by "14 CFR Part 23" and I am
looking to download it once in its entirety instead of the 500 subparts, one
at a time...
